如何在Mac系统上使用Windows US-International键盘布局？

Absolutely—though Apple’s built-in "U.S. International - PC" layout falls short of matching the behavior you’re used to on Windows/Linux/ChromeOS, there are reliable ways to get a true US International layout on Mac. Here are the most practical approaches:

1. Build a Custom Keyboard Layout (Exact Match) #

If you want a 1:1 replica of the US International layout from other systems, use a dedicated layout editor:

• Ukelele (free, user-friendly):
  • Download and launch Ukelele, then create a new layout based on the default "U.S." template.
  • Remap your right Alt key to act as AltGr (the standard name for this modifier on non-Mac systems).
  • Configure all the key combinations you need: map AltGr + e to é, AltGr + c to ç, AltGr + 2 to €, and set up dead keys for accents like ^ (to make ê) or ` (to make è).
  • Export the layout file, install it to either ~/Library/Keyboard Layouts/ (user-specific) or /Library/Keyboard Layouts/ (system-wide), then enable it in System Settings → Keyboard → Input Sources.
• For those who prefer Apple’s native tools, the older Apple Keyboard Layout Creator works too, but its interface is clunkier compared to Ukelele.

2. Use Karabiner-Elements (Flexible Key Remapping) #

If you don’t want to build a full layout, Karabiner-Elements lets you tweak your existing keyboard to mimic US International behavior:

• Install Karabiner-Elements, then open its configuration window.
• Create a new rule that repurposes your right Alt key as an AltGr modifier.
• Add specific key mappings: for example, set right_option + e to output é, right_option + ; to output ñ, and right_option + 5 to output £.
• Enable the rule, and your right Alt will now function exactly like it does on Windows/Linux/ChromeOS, supporting all the quick symbol inputs you’re used to.

Why the Native "U.S. International - PC" Layout Isn’t Enough #

Apple’s pre-installed layout only implements basic dead key functionality (like pressing ' then e to get é), but it doesn’t treat the right Alt key as a dedicated AltGr modifier. This is the core mismatch: on other systems, US International relies on AltGr for direct, one-step symbol inputs, rather than forcing you to use dead key sequences for every accented character or special symbol.
